摘　　要：三峡库区是地质灾害的多发区,其中滑坡灾害尤为常见,因此有效地管理各种滑坡信息对于滑坡预测与评价有重要的意义.鉴于传统数据库不能管理空间数据的局限性,采用空间数据库技术有利于对滑坡的各种空间信息进行管理.从空间数据库的设计思路、内容、建库技术路线以及数据库功能4方面介绍了基于GIS(Geographic Information System)的三峡库区滑坡空间数据库系统的设计.Three Gorges reservoir area is a universal place of geological disasters of which landslide hazards are particularly common.Therefore,the effective management of informations is significant for landslides forecast in this area.However,the traditional databases have the limitation that it cannot manage the spatial data well;managing a variety of landslide spatial information by using spatial database is a useful way instead.A GIS-based landslide spatial database design for the Three Gorges reservoir area is introduced from four aspects： the design ideas of the spatial database,content,the technology of building a database as well as the function of database system.
